The addition of amines to diisobutylaluminum-imine complexes. Preparation of NPS R-568 Hydrochloride
摘要:
A facile procedure for the preparation of secondary and tertiary amines from nitriles has been developed. The addition of amines to diisobutylaluminum-imine complexes derived by treating nitriles with DIBAL-H was found to proceed in moderate to good yields and was used to prepare NPS R-568 (1) hydrochloride, a potent calcium receptor agonist.
